Especially after he just tried to take the Ring from Frodo, you think the other hobbits are fucked and then Boromir jumps out the trees like a fucking badass and kicks that Uruk in the balls, and just starts reaping them... the movie actually underestimates how many Uruks Boromir fought off, when Aragorn found him, he was sitting with his back to a tree and "over a score" of dead Orcs broken at his feet, he fought till his sword broke, even wounded to death, even in the movie, when he gets hit he keeps fighting with fucking arrows the size of broom handles in him... I loved that scene, even though I knew what happened next (I've been a Tolkien fan since the early 80's when I first read it) you're still rooting for him to hold out till Aragorn gets there... at least he got his chance at redemption after breaking the Fellowship.
Boromir wasn't a bad guy, he was desperate to save his people, and had grown up hearing legends of "Isildurs Bane", how it was some mighty weapon, he didn't know what it really was, he just didn't understand throwing away the "Ultimate Weapon" when it was Gondors darkest hour, and the Ring always preyed on the weaknesses in the hearts of men.
That scene with Aragorn as he's dying, and asks Aragorn to save his people is a bonafide mans man moment. Tolkien fought in some of the worst and bloodiest battles in human history, the Somme, Ypres, he knew what brotherhood and friendship forged through hardship was.
Its partly what I find so fucking gross and offensive when faggots try to turn Frodo and Samwise into a pair of sodomites, purient fucks with their minds in the gutter totally miss the whole point of the Ringbearers story.
